FIELD

The disclosure relates to a device and a method for managing urinaryincontinence. Specifically, the disclosure relates to a urinary catheteror plug for voiding urine controllably while preventing urine leakageand reducing urinary tract infections.

BACKGROUND

The bladder stores urine. During urination, bladder muscles squeeze thebladder, forcing urine out of the bladder through a passage called theurethra. Sphincter muscles around the urethra function as a valve. Whenthe sphincter muscles relax, the urethra is open, and urine can flow outof the bladder. When the sphincter muscles contract, the urethra isclosed, and urine cannot flow out of the bladder.

Urinary incontinence is the involuntary leakage of urine. Urinaryincontinence can happen when the bladder muscles suddenly contract, andthe sphincter muscles are not strong enough to maintain the close of theurethra. Urinary incontinence may also occur if there is a problem withthe nerves that control the bladder and urethra.

Urinary incontinence is a common and often embarrassing problemaffecting women and men of all ages. Urinary incontinence is more commonamong women than men. Types of urinary incontinence can include stressincontinence, urge incontinence, overflow incontinence, functionalincontinence, and mixed incontinence.

In an embodiment, the release device 117 is a valve. In anembodiment, the release device 117 is a palpitatable valve. As the fluidis released from the balloon 110, the balloon 110 deflates, and theurinary catheter 100 can be safely removed without causing urethralinjury. In an embodiment, the fluid is air. In an embodiment, the fluidis water. In an embody, the fluid is an antimicrobial solution. In anembodiment, the fluid is a saline solution.

The device can be removed by deflating the inflated balloon 110 locatedin the bladder and then gently pulling on the urinary catheter 100,which will release the platform 120.

The balloon 110 can be made from any suitable material. In anembodiment, the balloon 110 is made from a thermoplastic material. In anembodiment, the balloon 110 is made from an elastomer. In an embodiment,the balloon 110 includes a thermoplastic elastomer on its exteriorsurface. In an embodiment, the balloon 110 is coated with a siliconerubber.

In an embodiment, the platform 120 holds the balloon 110 in a sealingcontact with the neck of the bladder. In an embodiment, the balloon 110includes an adhesion surface provided on a surface 111 where the balloon110 contacts the neck and/or the internal orifice of the urethra whenthe balloon 110 is in place for managing urinary incontinence. In anembodiment, the adhesion surface adheres the balloon 110 to the neck andsealing gaps therebetween in a releasable and reusable manner. In anembodiment, the adhesion surface includes an adhesive discussed above.

The distance between the platform 120 and the balloon 110 can beconfigurable to fit different patients. In an embodiment, a retainer 125is provided between the platform 120 and the elongated body 101 foradjusting the position of the platform 120. The platform 120 can bemovable axially along the retainer 125. In an embodiment, the retainer125 includes ridges, and the platform 120 can slide axially along theridges. In an embodiment, the retainer 125 may be threaded, and theplatform 120 can move up or down along the thread by rotation. Theretainer 125 can retain the platform 120 at different positions of theelongated body 101 so that the urinary catheter 100 can fit differentlengths of the urethra.

In an embodiment, the retainer 125 is molded onto the elongated body101. The retainer 125 can be firm so that it can retain the platform120. In an embodiment, the retainer 125 is fixed on the elongated body101 by an adhesive or cement or the like. In an embodiment, the retainer125 and the elongated body are unitary one piece and constructed fromthe same material.

The platform 120 can also be preconfigured to have various distancesfrom the balloon 110 to fit various lengths of patients' urethra. In anembodiment, the urinary catheter 100 can be manufactured with differentdistances between the platform 120 and the balloon 110 to fit variouspatients' needs. In an embodiment, the urinary catheter 100 does notinclude the retainer 125, in an embodiment, the platform 120 is directlymolded on the elongated body 101. In an embodiment, the platform 120 isdirectly fixed on the elongated body 101 with an adhesive or cement orthe like.

The urinary catheter 100 can be inserted into the urethra and thebladder. After the balloon 110 is inflated through the inlet 112, theurinary catheter 100 is gently pulled so that the balloon 110 can be infirm contact with the neck of the bladder to seal the internal orificeof the urethra. The platform 120 is also advanced along with the urinarycatheter 100 to reach a suitable position on the urethral orifice. In anembodiment, the platform 120 is advanced until its adhesion surfacecontacts the external orifice of the urethra. The platform 120 thensoftens at body temperature, forming a waterproof seal with the externalurethral orifice.

Compared to the traditional Foley type catheter, the platform 120 canprevent urine leakage and reduce bacterial infections due to using aninflatable balloon alone for sealing, as the inflatable balloon of thetraditional Foley type catheter has drawbacks in allowing intraurethralleakage. Combining the platform 120 with the balloon 110 can ensureurine exits the bladder only through the urine passage 105 of theurinary catheter 100, not the urethra. The platform 120 and the balloon110 provide the urinary catheter 100 with advantages over thetraditional Foley type catheter, as it can minimize or prevent the urineleakage associated with the traditional Foley type catheter. Althoughthe traditional Foley type catheter may include a structure calledcollar, the collar is typically disposed outside of the urethra and notin contact with the distal end of the urethra. Thus, the collar isprimary for stabilizing the inflatable balloon, not for sealing.

The elongated body 101 can be divided into two portions: a proximalportion 160 and a distal portion 180. The proximal portion 160 can begenerally disposed within the urethra and bladder. In an embodiment, thedistal portion 180 is absent. In an embodiment, the proximal portion 160is firm and polished. The firmness of the proximal portion 160 enablesthe insertion of the urinary catheter 100 into the urethra and bladder.In an embodiment, the proximal portion 160 can have a hardness in arange of at or about 40 to at or about 100 on the Shore A scale ofhardness at the body temperature. In an embodiment, the proximal portion160 can also be slightly elastic to provide a comfortable wearingexperience. The distal portion 180 can be disposed outside the urethraand bladder. The distal portion 180 can be short in length so that it ishidden and does not interfere with the mobility of a user. In anembodiment, the distal portion 180 is soft and pliable. The softness andpliability of the distal portion 180 enables the urinary catheter 100 tobe worn without interfering with the normal activities of the user andwithout being evident. In an embodiment, the distal portion 180 can havea hardness in a range of at or about 0 to at or about 40 on Shore Ascale of hardness at the body temperature.

In an embodiment, the proximal portion 160 and the distal portion 180are a unitary one-piece construction. In an embodiment, the proximalportion 160 and the distal portion 180 are made from different materialsand molded together.
